Giant golden mole

Giant golden mole is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Giant golden mole rather than just read about it. In short: The giant golden mole (Chrysospalax trevelyani) is a small mammal found in Africa. At 23 centimetres (9.1 in) in length, it is the largest of the golden mole species.

Key takeaways

Giant golden mole belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Giant golden mole to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

The giant golden mole (Chrysospalax trevelyani) is a small mammal found in Africa. At 23 centimetres (9.1 in) in length, it is the largest of the golden mole species. This mole has dark, glossy brown fur; the name golden comes from the Greek word for green-gold, also the source of the name of the family, Chrysochloridae.

Characteristics The giant golden mole has a subterranean lifestyle. It has large claws around 17 millimetres (0.67 in) long and 7 millimetres (0.28 in) across the base, powerful forelimbs, no external tail or ears, wedge-shaped head, leather pad, and skin covering the eyes. It is approximately 208–235 millimetres (8.2–9.3 in) in length and 410–500 grams (14–18 oz) in weight. Its skin is dark and brown on the upper parts and faded on the underparts, sometimes with a darker line down the mid-throat. Its coloration is slightly darker on the head, with two dull yellow patches where the eyes would be, and a yellow patch around the ear openings. Its hair is longer and coarser than any other species of golden mole: about 20 millimetres (0.79 in) long, thick, with dense, woolly underfur.

Biology The largest, rarest, and most endangered of all 17 species of golden moles, the giant golden mole spends most of its time underground and is blind and deaf. It is nocturnal, hunting mostly at night, but also in some cool and cloudy daytime conditions. It is solitary; it does not form groups, despite some social behavior such as hibernating in others' burrows among the roots of trees in winter, only moving slightly to keep its body temperature in range and twitching to maintain body temperature while sleeping. Female giant golden moles give birth to one or two offspring at a time while it has stocks of food supply. The acanthocephalan Heptamegacanthus niekerki has been found parasitizing the giant golden mole by attaching to the wall of the rectum.

Diet The giant golden mole digs semi-permanent tunnels about 10 metres (33 ft) in length linked by surface runways for hunting food and may feed on the surface hiding in the leaf litter. It eats mainly millipedes and giant earthworms, but also crickets, cockroaches, grasshoppers, worms, and snails.

Habitat

The giant golden mole is a subterranean small mammal, living in chambers and passages underneath a very specific habitat, forests with soft soil, deep leaf litter layers, and well-developed undergrowth. The giant golden mole is endemic to South Africa, mostly in a restricted area in the Eastern Cape.

Population

Status The giant golden mole was classified as Endangered (EN) in 2010 on IUCN Red List of Threatened Species. The population is decreasing due to habitat loss resulting mainly from human activities affecting its habitat such as firewood collection, bark stripping, cutting for construction, overgrazing of livestock, and clearance of forest. Moreover, the giant golden mole is preyed on by domestic dogs in that area.

Conservation The giant golden mole currently receives little protection, and is not a main conservation target. Research is needed to protect this species and to assess the status and viability of the remaining populations.

Worked examples

Example 1 — a first encounter with Giant golden mole

Start with the simplest possible case. Write down what Giant golden mole claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Giant golden mole before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Giant golden mole ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Giant golden mole

In research: Giant golden mole appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Giant golden mole in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Giant golden mole is common in secondary-school and first-year university syllabi. It links to neighbouring topics Afrosoricida, Endemic fauna of South Africa, IUCN Red List endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Giant golden mole outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
